Brumbull, I have had two of them for about 4 years, a white one and a pink one, both now about 4 feet tall. I planted them to the same level as in the pot, give them some tomato type fertilizer in early Spring. You may have to stake them as they get bigger. I cut off the dead flowers but leave the leaves, as it looks quite nice just with just the leaves. Have tried to leave one flower until it grows seed pods and tried to sow the seeds, but it didn't work! Each spring cut of dead stems down to the lowest buds.
Hope this helps.
